#33110 restores the time scale UI field.

However, I'm not sure what plans @mrdoob has for the list of animation clips. When I understand #32869 (comment) correctly, a separate list of an object's clips in the OBJECTS tab is not wanted. So you must collapse the animation panel in order to select animation clips.

One issue of the current animation panel is that it's hard to manage multiple objects with animations since all clips are managed in a single global list.

I've added an additional commit (73211bc) in #33110 to fix that issue as well.
